Overview -This project implements a custom Real-Time Operating System (RTOS) for STM32 microcontrollers. The RTOS features a multithreading kernel that supports pre-emptive multitasking and round-robin scheduling.

Key Features

-Custom multithreading kernel

-Pre-emptive multitasking

-Round-robin scheduling

-Context switching implementation

-Task Control Block (TCB) management

-Custom stack management

-Register setup for task switching

-SVC and PendSV interrupt handling

Implementation Details

-Developed in C for STM32 microcontrollers

-Utilizes ARM Cortex-M architecture features

-Implements a priority-based scheduler

-Manages task states (Ready, Running, Blocked)

-Provides efficient context switching mechanism

Context Switching

-The RTOS implements context switching using:

-Custom Task Control Blocks (TCBs) for task management

-Efficient stack management for each task

-Proper register setup to preserve task state

-SVC (Supervisor Call) for system calls

-PendSV (Pendable Service Call) for scheduling
